Recent research suggests that a modified habit reversal procedure, including awareness training alone or combined with competing response training, is effective in decreasing speech disfluencies for college students. However, these procedures are potentially lengthy, sometimes require additional booster sessions, and could result in covariation of untargeted speaker behavior. We extended prior investigations by evaluating awareness training as a sole intervention while also measuring collateral effects of treatment on untargeted filler words and rate of speech. We found awareness training was effective for all participants without the use of booster sessions, and covariation between targeted filler words and secondary dependent variables was idiosyncratic across participants.

Recent literature supports using an awareness training treatment package to decrease speech disfluencies for college students delivering short speeches. This package includes identifying speech disfluencies first via a video recording (video training), then during in vivo speech practice (in vivo training). However, the literature lacks an evaluation of these subcomponents, which poses a barrier to better understanding the efficiency, social validity, and potential underlying behavioral principles of awareness training. We conducted an add-in component analysis with 8 college students by implementing either video or in vivo training first, evaluating treatment effects via a posttest, then implementing the remaining subcomponent, if warranted. We found that in vivo speech practice may be sufficient for reducing disfluencies for some participants, but a treatment package including the sequential application of both video and in vivo training is more likely to result in marked behavior change.
